Reddy Heater 50,000 BTU Forced Air Kerosene Heater, Diesel - RFA50-V3

The Reddy Heater RFA50-V3 is a forced air heater designed to bring fast, dependable warmth to cold workspaces, job sites, and outdoor project areas. Generating 50,000 BTUs of heat with an airflow rate of 175 CFM, it is built to warm spaces up to 1,200 square feet quickly and evenly.

Fuel versatility is a major advantage with this model. Rather than locking you into a single fuel source, it operates on kerosene, diesel, #1 and #2 fuel oil, JP8, or jet fuel. Combined with a 5-gallon tank capacity, it delivers an extended run time of up to 14 hours, easily covering a full workday without constant refueling.

Operation is straightforward thanks to a one-touch electronic start. Built-in safety features include automatic flame-out shut-off and overheat protection, providing peace of mind during extended use. The durable, heavy-duty housing is paired with an easy-lift handle and a compact footprint, making it simple to transport from one site to another.

As for limitations, heating coverage tops out at 1,200 square feet, meaning larger industrial spaces will require a higher-capacity unit. The listing also does not provide specific physical dimensions or the dry weight of the unit.

Verdict: The Reddy Heater RFA50-V3 is an excellent choice for contractors and DIYers needing long-lasting, portable heat for medium workspaces. Its multi-fuel compatibility and 14-hour tank make it a practical heating solution for demanding workdays.
